+## Current Content Plan: Cloudpack Series
+
+Source: ~/workspace/wundler/ (kenotron-ms/cloudpack on GitHub) + architect brief + exec summary
+
+The core idea: the bundle is not a file, it's a query against a continuously-maintained
+module graph. The architecture maps native linker innovations (ThinLTO, mold, BOLT/Propeller)
+to JavaScript bundling at Microsoft Teams scale (50k+ modules).
+
+| # | Title | Angle | Visuals Needed |
+|---|-------|-------|----------------|
+| 1 | The Bundle Is Not a File | Linker-world analogy. ThinLTO/mold/BOLT mapped to JS bundling. "Database, not compiler." | Architecture: the 3-phase pipeline. Side-by-side: linker innovation → bundler equivalent. |
+| 2 | The 2KB Module Summary That Replaced a Full Parse | ModuleSummary as the core data structure. 25x compression. Content-addressed cache. | Diagram: source file (50KB) → ModuleSummary (2KB). The rayon parallel loop. |
+| 3 | Dead Code That Actually Stays Dead | Two-layer tree-shaking: module-level (conservative) + function-level (aggressive via call-edge graph). SideEffectMarker AST analysis. | Flow: BFS reachability + Tarjan SCC + call-edge DCE walk. Before/after module counts. |
+| 4 | The Service Worker as ld.so | Adaptive Bundle Service. Delta manifests. Browser tells server what it has, server returns only what's missing. | Architecture: CDN chunks as shared libraries, SW as dynamic linker. Delta computation flow. |
+| 5 | Your Users Are Teaching the Bundler | Profile-Guided Optimization from real browser sessions. C³ co-request clustering. SQLite co-request matrix. Prefetch without rebuild. | The feedback loop: browser sessions → JSONL → SQLite → C³ clustering → manifest hints. |
+| 6 | Signing Manifests, Not Code | Ed25519 signing of chunk hashes. Threat model: ABS compromise ≠ code injection. PGO fields excluded from signature. | Security model diagram: what's signed, what's not, what an attacker can/can't do. |

+Key numbers for receipts:
+- 10k modules warm rebuild: 604ms analysis-only
+- 50k modules in memory as summaries: ~100MB (fits L3 cache)
+- ABS delivery: ~50% CDN bandwidth saved per deploy
+- 50k modules, 10k DAU, 1% weekly churn: saves ~47 GB/week
